Considering the viscous interaction between the kernel and the air inside the grain the paper shows the dynamic tortuosity function in grain . considering the thermal exchanges between the kernel and the air the paper shows the dynamic permeability function in grain 考虑准多孔介质声传播中存在空气与颗粒间的粘滞力和惯性力,推导出准多孔介质中孔隙动态曲折度函数表达式。
This system included three parts : the first part was the establishment of 3d model buildings and conversion of the format for them , and then carried these 3d model randomly used java3d ; the second part was to research the scene simulation technology and provide a multifunction method to establish random hill 、 water and lawn , the characters of these natural scene could be controlled by some parameters ; the third part set up database management system , that system could 3d data of the random scene , so it could provide convenient and maintenant for the whole system 该系统包括以下几个关键部分:第一部分是三维建筑模型的建立及格式转化,然后把转化的格式进行存储,最后利用java3d技术对这些三维模型进行随机的调用;第二部分是研究当今视景仿真技术及其主要方法,提出多功能算法,利用java3d技术,生成随机的山、水、草地等,同时,还提供了交互式功能,用户可以利用可控参数对这些自然场景曲折度和宽度进行控制,此外,用户还可以对场景进行浏览,实现视点的移动、旋转,以及碰撞后视点的调整。
